Node-Octane

A Node.js wrapper for the Open Text ALM Octane and ValueEdge REST API.

Installation

Install via npm

$ npm i @microfocus/alm-octane-js-rest-sdk

Example

Please note that for the first time use, you need to do Update client API first.

const Octane = require('@microfocus/alm-octane-js-rest-sdk').OctaneVanilla

const octane = new Octane({
  protocol: "https",
  host: <HOST>,
  port: <PORT>,
  shared_space_id: <SHARED_SPACE_ID>,
  workspace_id: <WORKSPACE_ID>,
  routesConfig: <ROUTES_CONFIG_FILE_PATH> | <ROUTES_CONFIG_JSON_OBJECT>
})

octane.authenticate({
  username: <USERNAME>,
  password: <PASSWORD>
}, function (err) {
  if (err) {
    console.log('Error - %s', err.message)
    return
  }

  // get all defects
  octane.defects.getAll({}, function (err, defects) {
    if (err) {
      console.log('Error - %s', err.message)
      return
    }

    console.log(defects.meta.total_count)
    defects.forEach(function (defect) {
      console.log(defect)
    })
  })

  // get 10 defects in places 10 – 19
  octane.defects.getAll({limit: 10, offset: 10}, function (err, defects) {
    console.log(defects)
  })

  // get low severity defects
  const q1 = Query.field('name').equal('Low')
  const q2 = Query.field('severity').equal(q1)
  octane.defects.getAll({query: q2}, function (err, defects) {
    console.log(defects)
  })

  // create a defect
  const defect = {
    name: 'defect',
    parent: aWorkItemRoot,
    severity: aSeverity,
    phase: aDefectPhase
  }
  octane.defects.create(defect, function (err, defect) {
    console.log(defect)
  })
  
  // create multiple defects
  const defect1 = {
    name: 'defect1',
    parent: aWorkItemRoot,
    severity: aSeverity,
    phase: aDefectPhase
  }
  
  const defect2 = {
      name: 'defect2',
      parent: aWorkItemRoot,
      severity: aSeverity,
      phase: aDefectPhase
    }
  octane.defects.createBulk([defect1, defect2], function (err, defect) {
    console.log(defect)
  })

  // update a defect
  const name = 'defect test updated' + Math.floor((Math.random() * 100) + 1)
  client.defects.update({id: defectIDs[0], name: name}, function (err, defect) {  
    console.log(defect)
  })
  
  // update multiple defects
  const name1 = 'defect1 test updated' + Math.floor((Math.random() * 100) + 1)
  const name2 = 'defect2 test updated' + Math.floor((Math.random() * 100) + 1)
  client.defects.updateBulk([{id: defectIDs[0], name: name1}, {id: defectIDs[1], name: name2}], function (err, defect) {
    console.log(defect)
  }

  // get a defect
  octane.defects.get({id: 1001}, function (err, defect) {
    console.log(defect)
  })

  // delete a defect
  octane.defects.delete({id: 1001}, function (err) {
    if (err) {
      console.log('Error - %s', err.message)
    }
  })
})

Authentication

The Octane API allows to sign in with user credential or API key.

// user credential
octane.authenticate({
  username: <USERNAME>,
  password: <PASSWORD>
}, function (err) {
  // handle sign in result
})

// API key
octane.authenticate({
  client_id: <CLIENT_ID>,
  client_secret: <CLIENT_SECRET>
}, function (err) {
  // handle sign in result
})

Query

The Octane REST API supports entities querying by filtering based on field values. To filter, use a query statement, which is comprised of at least one query phrase.

The client API provides the Query module to help you build the query, rather than writing the complex query statement.

const Query = require('@microfocus/alm-octane-js-rest-sdk/query')

// query statement: "id EQ 1005"
const query = Query.field('id').equal(1005)
octane.defects.getAll({query: query}, function (err, defect) {
  console.log(defect)
})

...

// query statement: "name EQ ^test*^"
const query = Query.field('name').equal('test*')

// query statement: "user_tags EQ {id EQ 1001}"
const query = Query.field('user_tags').equal(Query('id').equal(1001))

// query statement: "user_tags EQ {id EQ 1001||id EQ 2005}"
const query = Query.field('user_tags').equal(Query.field('id').equal(1001).or(Query.field('id').equal(2005)))
// or use the shorthand or() method
const query = Query.field('user_tags').equal(Query.field('id').equal(1001).or().field('id').equal(2005))

// query statement: "user_tags EQ {id EQ 1001;id EQ 3008}"
const query = Query.field('user_tags').equal(Query.field('id').equal(1001).and(Query.field('id').equal(3008)))
// or use the shorthand and() method
const query = Query.field('user_tags').equal(Query.field('id').equal(1001).and().field('id').equal(3008))

// query statement: "user_tags EQ {id EQ 1001};user_tags EQ {id EQ 3008}"
const query = Query.field('user_tags').equal(Query.field('id').equal(1001)).and(Query.field('user_tags').equal(Query.field('id').equal(3008)))
// or use the shorthand and() method
const query = Query.field('user_tags').equal(Query.field('id').equal(1001)).and().field('user_tags').equal(Query.field('id').equal(3008))
// or use the sub query
const query1 = Query.field('user_tags').equal(Query.field('id').equal(1001))
const query2 = Query.field('user_tags').equal(Query.field('id').equal(3008))

// query statement "id BTW 1..3" - notice that there are two parameters
const query = Query.field('id').between(1,2)

// query statement "id IN 1,2,3" - the parameter has to be an array
const query = Query.field('id').inComparison([1,2,3])

const query = query1.and(query2)

// for null use either Query.NULL for non-reference fields or Query.NULL_REFERENCE for references (Query.NONE still exists for backwards-compatibility
// and is the same as Query.NULL_REFERENCE)
const query1 = Query.field('string_field').equal(Query.NULL)
const query2 = Query.field('reference_field').equal(Query.NULL_REFERENCE)

Attachment

To create an attachment, you must provide the file's absolute path.

...
const attachment = {
  name: 'attachment.txt',
  file: attachmentFile, // the file's absolute path
  owner_work_item: anWorkItem
}
octane.attachments.create(attachment, function (err, attachment) {
  console.log(attachment)
})
...

The attachment has both entity data and binary data. To get the attachment's entity data, call attachments.get(); to get its binary data, call attachments.download().

...
octane.attachments.get({id: attachmentID}, function (err, attachment) {
  consoloe.log(attachment)
})

octane.attachments.download({id: attachmentID}, function (err, data) {
  // data is the stream
  consoloe.log(data.toString())
})
...

Update client API

The Open Text ALM Octane REST API is fully metadata-driven. When the Octane REST API is updated, you can update the client API from the metadata.

Create a configuration file (eg octane.json) file for updating client API. It defines the Octane server's configuration and user credentials.

Note that by default headers are not enabled. To enable any header, add the key(s) and value(s) as a value for the "headers" key in the below configuration. As a header example, you could use the key ALM_OCTANE_TECH_PREVIEW with true/false as possible values.

$ cat > octane.json << EOH
{
  "config": {
    "protocol": "http",
    "host": "<HOST>",
    "port": <PORT>,
    "shared_space_id": <SHARED_SPACE_ID>,
    "workspace_id": <WORKSPACE_ID>,
    "headers: {
        <key> : <value>
    }
  },
  "options": {
    "username": "<USERNAME>",
    "password": "<PASSWORD>"
  }
}
EOH

Send the path to the created configuration file to generate_default_routes.js

$ node scripts/generate_default_routes.js /path/to/octane.json

The client API is defined in routes/default.json file. When you run this script to update the client API, you actually update the routes/default.json file.

You can copy this file to any other places (a place under the control of VCS for example), and pass the file's absolute path to the client constructor to use it, see Example.

The routes/meta.json file defines the minimal client API. It can't be changed or deleted.

This can be done also by using the generateDefaultRoutes function which returns a promise. To wait for the generation use the await keyword when calling the function as seen below.

try {
  await generateDefaultRoutes(configurationJSON, doNotOverwrite)
  octane = new Octane(...)
} catch (error) {
   //handle error
}

Update client API documentation

When the routes/default.json file is updated, you'll want to update API annotation file:

$ mkdir -p doc
$ node scripts/generate_api_annotations.js

Then you can create the client API documentation:

$ npm install apidoc
$ node_modules/.bin/apidoc -f doc/apidoc.js -o apidoc/

Tests

Run all tests

$ npm test

Or run a specific test

$ npm test test/query.js

The octane.json file is required for running the integration tests. If it doesn't exist, the integration tests will be skipped.

$ cat > octane.json << EOH
{
  "config": {
    "protocol": "http",
    "host": "<HOST>",
    "port": <PORT>,
    "shared_space_id": <SHARED_SPACE_ID>,
    "workspace_id": <WORKSPACE_ID>
  },
  "options": {
    "username": "<USERNAME>",
    "password": "<PASSWORD>"
  }
}
EOH

npm test test/integration

Please Note When running integration tests and these include attachments the tech preview api needs to be enabled otherwise the attachments will fail
